Introduction: Obstacle Avoiding Circuit

This is simple circuit named Obstacle Avoiding Circuit for Robot . With the help of this circuit the will move left whenever there will be a obstacle in front of Robot. It will turn left whenever the distance from Ultra Sonic Sensor to the object is less than 20cm . If the distance from Ultra Sonic Sensors to the object is more than 20 cm then it will move forward .

Step 1: Components

So, to make the Circuit we only need 5 things which are :-

1 Breadboard (Quantity 1)

2 Arduino (Quantity 1)


3 L29 3D (Quantity 1)


4 Ultra Sonic Sensor (Quantity 1)


5 Motors (Quantity 2)

Step 2: Connection

Do the connections as same as the picture. You can use TinkerCad software or by using real materials but you have do the same connections in both cases.

Step 3: Coding

Do the coding as same as the picture if you want to the left coding.
